Take note it's a four link front end, so the front axle will not arc. The caster will be adjustable to a point.

This front end is higher off the ground and will have the same amount of travel as my Kia Boy car, which should be about three inches. Looking under my car there's 3/8's inch before it starts to load the rubber snubber.

I've decided to use the original tie rod locations on the spindles. I'll fabricate bolt on brackets that will locate a hole above the center line of the axle, like an upper tie rod location. Bolt and sleeve the two together with a vertical bolt and spacers, to locate the heim joint directly in the middle of the four link bars on either side. Instead of an outer tie rod.

The photos are development in progress and probably look deceptive to the design goal.

The way to do a rack with a straight front axle is to mount the rack to the axle (it moves up and down with the axle). That way, when one tire is compressed or "bumped" (it doesnt have to be an actual bump- this happens when you make a turn at speed or hit the brakes) the spindle for the wheel isn't turned (bump steer). because the rack moves, you'll need to have a slip joint in the steering column somewhere to accomdate movement.

If you want to go old school, do a cross steer setup. (the Speedway Motors catalog has pics). I think I saw somewhere on this site how to do DIY reverse a corvair box...

The picture you posted with a rack looks like an asphalt modified. This car has an independant front suspension, with control arms (A-arms). The tie rods on the rack move in the same arc as the control arms.

It's not clear to me from the pictures, but does the leaf pring connect to the axle with shackles? What I'm getting at is with a four bar front end, you need a panhard bar or the leaf spring needs to be mounted to keep the axle in alignment (left to right). hope this makes sense. sorry if I'm stating the obvious.

not trying to be down on your cool project, just trying to offer advice.

Rod's length of about one third of the length of your gun if I remember correctly. This means that when you play bump, your gun will move a very large arc, and a much smaller arc in the rod. Tera Money This is equivalent to bumpsteer!
